A finger 22 carriedby support I5. has one endthereof inalignment with one of the grooves and is adapted to ride theflat sheets and urge them against the wheel.

The adhesive applying wheel IS-rotates in a removable-container`23holding an adhesive uid. Further detailed particulars regarding theadhesive applyingmeans will be given hereinafter.

The sheet feeding means moves the flatsheets to the end I of the tablewhere guides or alignersare provided to. properly position each sheet.'Ihelongitudinal guide 24. is adjustably carried onlrods 25,.slidablysupported in-brackets 26, and transverse guide 21 is.slidably carried onrod 28 fixed to cross bar 29.

ForY accurate alignment of the sheets, means for jogging orimparting anYintermittent movement .to the guides is provided-on the longitudinalguide-by diagonally slotted ends 39 on rods 25, arms V,3l havingpinsworking in said slots, the arms being secured to shaft 32 suitablyYcarried by the table, and supporting one endY of ythe-cross bar 29.Spring 33 normally urges the shaft 32 in one direction, and other means,hereinafter disclosed, arefprovided for urging, the shaft in theopposite` direction to actuate. the arms 3l and cross bar 29 to.jog thesheet at the `guides for proper alignment. The other end of the.crossbar 29 is resiliently mounted in thetable I at 34.

Suitable sheet holddowns 35 may be adjustably carried on rods which inturn are transversely adjustable on rods 31 carried in brackets 26.`

In the carbon paper feeding means a roll of carbon paper 33 is carriedon suitably journaled shaft 39,7a spring 39 keeping the roll at propertension a'ndfin proper feedingzposition. The carbon paper passes alongguide 40 and between feed rollers 4I and 42. An arcuate guide 43 directsthe carbon paper around the roller 4I and onto guide 4,4 from whence it`passes between knives 45l and 46 onto a carbon paper receiving table 41.The knife 45 may be carried by the table frame I and the knife 46 by thetable 41. The carbon paper receiving table 41 is suitably pivoted at 48and is adapted to be intermittently rocked by mechanism hereinafterdisclosed.

To maintain proper cutting relation between the knives, an adjustablefriction plate 41', carried by the table frame I, is adapted to bearagainst the end of the table 41 opposite the knives.

After the carbon` paper is severed and secured to the flat sheets, thecombined sheet and carbon is transferred to. a vertically movablereceiving table. 49. carried on standard 50 sleeved in cylinder 5I ofcross frame 52 and normally urged upward by spring 53. (See Figs. 3 and4.)

To hold receiving table 49 locked against upward movement as it movesdownwardly we have provided a lever or dog 54, operatingv in slot 55 ofcylinder 5I and having offset pivot 56. The leverv 54 is normally urgedagainst the standard 50 by spring 51..

For assisting in the alignment of the sheets on theY receiving table 49,adjustable guides 58 and 59 may-be provided, said guides beingpositioned in slotted openings 60 and 6I of the receiving table,` thebinding means forminga guide for one edge of the sheets.

To transfer the fiat sheets and carbon paper to the receivingy table 49we have provided a reciprocating carriage 62 having a sheet pickup orsuction bar 63 with suction openings 64 in the bottom thereof. (See Fig.10.) To the carriage are secured rods 65 vertically slidable in heads 66horizontally movable onrods 61 carried by the table frame I. The lowerend of each rod 65 is secured to plates68 and the plates andcarriage arenormally urgedfupwardA by springs 69. The reciprocating mechanism forthe carriagewill be described hereinafter. The carriage is depressedinto sheet pickup position by the cams v contacting the lroller 1I. onplates 68 and forcing said plates and attached rods 65 downwardly.

As shown in Fig. 10, a swinging sheet guide 12 is provided and isadapted to bey moved out ofthe path ofthe suction bar 63 by meanshereinafter related. A suction bar holddown member- 63 is alsoprovidedon thetable frame for contacting the, suction bar during sheetpickup. The suction bar 63gcarries a` suction relief Valve 13 adapted tobe operated during. sheet deposit by. slidable member 14..striking xedstop 15.'

Immediately upon alignment and during deposit ofthe transferred sheets,binding means are adapted tocome into play. This binding meanscomprises. a frame 16v carried by rods 11 arranged for vertical movementin bearings 18 and normally urged upwardlyby springs 19.. This frame hasa plurality of` vertical fingers V8E) abutting oneedgeofithe receivingtable 49, the fingersghaving, angular ends 8|. adapted to bear againstthe. sheets and lcarbon paper onthe table 4 9,wh en the frame 16,isdepressed.

The. binding` frame 16V is .provided with offset hook portionsSZ (see.Figs. 3 and4) in which plates.68.of carriage 62 are adapted to enterduring` sheet deposit, saidplates. and theV attached carriage beingadapted to be moved downwardly. Guide ears 62 on the carriage 62 areadapted to engage and movevertically in guides 62 on the table frame topositively guide thel carriage-62 dur-ing vertical deposit movement. 7

It will be noted that -the strain is taken by the binding means, thetransfer carriage merel'yfbeing-carried downwardly with the frame 16 andnot exerting `any force against the sheets onl the receiving ta'ble 49.vOperating means for the .binding means will be described hereinafter.

A hopper or sheet striker is provided by flexible ngers 83 carried onshaft 84, rotatable by pinion 85 and rackr 86, the operating means forsaid rack being disclosed later. vThe fingers 83 are adaptedtoberapidly'swung arcuately -between the binding fingers 80 to strike Ytheassembled sheets after the reciprocating'carriage has deposited eachsheet and' has left deposit position or at least has moved cleared ofthe path of the flopper fingers 8,3. A flopper strike bar 81 of suitablesound deadening material may be secured to the table frame I.

The driving source for all the moving mechanisin may be an electricmotor 88 or any other suitable power unit, geared down through reductionunit 89 driving shaft 90 suitably journaled in the table frame I. Aswitch 88 for controlling the current source to the moto-r is shown butany suitable switching means Ymay be used, such as a foot control or thelike.

The sheet introducing table 5 isactuated by cam 9| on shaft 90, said camcontacting roller 92 on upright connecting rod 93 pivotally securedtothe table 5. (Fig. 9.)

The sheet feeding pulleys and belts I and I2 are driven by bevel gear 94on shaft 90, driving gear 95, sprocket 96, chain 91, and sprocket 98 onshaft II.

The sheet perforating .means are driven by bevel gear 99 meshing withgear |00 on shaft II and Ygear, |0| meshingwith gear |02 on shaft |03onwhich the perforating disc is mounted.

In theadhesive applying means it is necessary that the wheel I8 andcontainer 23 be removable andit is also necessary that means be providedto render the adhesive applying means inoperative by moving the same outof the path of the sheets.A It is to be understood that this is doneordinarily only during the feeding of the first sheet for thestart ofeach set, which sheet obviously does not require any carbon paper andtherefore no adhesive.

Toward this end We have provided on the hub of thewheel I8, a pin |04adapted to engage groove in shaft I9 and to enter leg |06 of saidgroove. The container 23 is provided with a collar |01 having slot |08,thecollar |01 being adapted to sleeve over collar |09 of bracket IIO,the shaft I9 bearing in said collar |09 and the slot' |08 in collar |01being adapted to engage the bracket 0. The bracket |I0 is provided witha vsecond collar III which is sleeved on shaft |03 of the perforatingdisc I1. Shaft |9 is driven by pulleys. I|2 and belt ,I I3.

To retain the adhesive applying assembly in raised position we haveprovided a yoke I I4 carried by offset arm |I5 of rod IIB, and bearingagainst the collar |01.

The rod ||6 is suitably supported for vertical movement, is normallyurged upward by springs II1, and terminates at its base with a suitablefoot pedal II8. As shown in Figs. 1, 6 and 9, it will be notedA that theoffset arm'may be Aswung clear of 4the bracket IIO to facilitate removalof the adhesive container and wheel.

The sheet joggers are motivated by cam ||9 on disc IIS' carried by shaft9|)l said cam actuating `a. rocker arm |20 on shaft |20 suitablyjournaled tothe table frame and extending upwardly to terminate in anarm |2| adapted to bear against depending leg |22 `of 'cross bar 29.Movementof the cross bar will cause longitudinalinovement of thefshaft32, causing pins on armsy 3| to slide in slotted ends 30 of rods 25,forcing said rods inwardly, providing for an intermittent jogging of theguides 24 and 21.

In the carbon paper feeding mechanism the perforating disc shaft |03extends transversely of the table frame I and carries pulley |23 drivingpulley |24 through belt |25. The pulley |24 freely rotates on shaft |26of feed roller 4I, said shaft carrying gear 4I on the opposite side ofthe table in mesh with gear 42' on shaft 42 of roller 42.

The pulley |24 carries a clutch cone |21 adapted to engage taperedrecess in drum |28 which is secured to the shaft |26. A yoke bracket |29carries clutch actuating lever |30, the other end of which isoperatively engaged with solenoid |3I. v-A brake shoe |32 is operativelyrelated to the drum |28 and is carried on rod |33 slidably mounted'inbracket |34, the shoe |32 being normally urged against Vthe drum byspring |35, a pivoted lever |36 being adapted to slidably actuatethe'rod |33, the end |31 of said leverbeing I operatively connected to asolenoid |38.

In connection with the solenoids and the related mechanism which theyactuate, attention is invited to the circuit diagram in Fig. 8 as wellas to the other views showing carbon paper feed control mechanism.

One of the novel features of our machine lies inthe use of the ilatsheet being fed to automatically start and stop the carbon paper feedingmeans.

Although other means may be employed with equal results we havepreferred to illustrate an electric eye or photoelectric cell as a meansfor controlling the starting and stopping of the carbon .paper feed.

As shown in the various views and particularly in Fig. 5, aphotoelectric cell |39 is mounted above the table I and the rays from anincandescent bulb |40 are adapted to pass through opening |4I in thetable, the cell |39 being focused to catch the rays.

As far as, the photoelectric cell is concerned, the circuit usedtoconvey the energy from said cell is standard land well known, a relay|42 and switch control |43 being connected in the circuit and energizedby action of the photoelectric cell.

One conductor |44 of the current source line is connected to one side ofthe switch I43, the other conductor |45 being connected to each of thesolenoids A |3| land |38. Another conductor |46 connects the twosolenoids and the switch |43.

Under normal conditions when there is no sheet in the feeding means theopening |4| is unobstructed and the rays from the incandescent bulb passtherethrough and actuate the photoelectric cell which, in turn, actuatesth-e relay and switch to maintain an open circuit, whereby the solenoidswill be inoperative and the clutch will remain disengaged andthe brakeengaged to prevent carbon paper feeding.

Howeverthe moment the light ray is broken or obstructed so that itcannot reach the photoelectric cell, the relayand switch will operate toclosethe circuit and operatethe solenoids for immediate engagement-ofthe clutchand release of the brake.

The purpose for providing a brake is to insure immediate stopping of thecarbon feed rollers upon passage of a sheet beyond the,l light rayV andupon release of the clutch.

As heretofore explained, when feeding the initial sheet for each set, itis not desired to apply an adhesive thereto orto supply carbon papertherefor. However, while the initial sheet is approaching the adhesiveapplying means, the preceding sheet is passing through the carbon paperfeeding stage, and it is necessary to continue the carbon paper feedingoperation for said preceding sheet. In other words, it is desired tooperate a manual control for moving the adhesive applying means out ofthe path of the initial sheet without rendering the carbon paper feedingmeans inoperative while the preceding sheet is passing through thecarbon paper feeding stage. But it is necessary to render and holdinoperative the carbon paper feeding means while the initial sheet ispassing through the carbon paper feeding stage.

Toward this end we have provided the mechanism heretofore described forraising and lowering the adhesive applying means, and in connectiontherewith we have provided, as a preferred method for accomplishing ourpurpose, a mercury switch |41 mounted for tiltable movement andincorporated in the circuit to the solenoids. A lever |48 is adapted totilt the Switch |41 and is secured to a resilient lever |49 having adetent |50 engageable in slot |5| of drum |52 on shaft 90. The resilientlever |49 is carried by arm |53 on rod ||6.

In operation, when the foot pedal H8 is depressed the adhesive applyingmeans will irnmediately be removed from the path of the sheet being fed.However, the carbon paper feeding mechanism will continue to beoperative bythe preceding sheet passing below the photoelectric cell,until the detent |50 riding the outer periphery of drum |52, upondepressing of the pedal, enters the slot permitting downward movement oflever |48 and subsequent tilting of the mercury switch |41 for openingof the circuit in which the clutch and brake operating solenoids areconnected. The slot |5| and drum |52 are so arranged and timed as toprevent entrance of the detent |50 until the preceding sheet has passedthrough the carbon paper feeding stage. Conversely, upon release of thefoot pedal for return of adhesive applying means to Operating positionfor the sheet following the initial sheet, the carbon paper feedingmeans will be retained in inoperative position during passage of theinitial sheet through said carbon paper feeding stage, the detent |50being urged against the inner periphery of the drum |52 until inalignment with and released through the slot |5|, said release occurringafter the initial sheet has passed through the carbon paper feedingstage and before the following sheet has reached the carbon paperfeeding stage. Release of the detent |50 will cause the mercury switch|741 to close the circuit between the solenoids and the switch |43,permitting normal opening and closing of the circuit by operation of thephotoelectric cell.

The pivoted carbon paper receiving table 41. is rocked or actuated bylever |54 and link |55 pivotally secured to table 41, the lever |54being carried on shaft |56 having rocker arm |51 and roller |58contacting and rockable byk cam wheel |59 on shaft |60l rotatable bysprocket |6|, and chain |62 on sprocket |63 of shaft 90. yA spring |64normally urges rocker arm |5| downwardly to retain roller |58 againstthe cam wheel |59.

The transfer carriage 62 is adapted to be reciprocated by leverextension |65 on disc H9', said extension pivotally carrying lever |66having a slotted end |61 slidably connected to lever |68. Said lever |68is carried on a shaft |68 and sleeve arms |69 are carried at both endsof shaft |68. Rods are slidably positioned in the arms |69 and haveforked ends in pivotal connection with heads 66 of the carriage 62.

The slotted connection between lever |66 and lever |68 provides for aslight time delay in carriage reciprocation at the moment of sheetpickup and sheet deposit, and to prevent sudden jars and strains whenthe ends of the slot |61 are reached we have provided a uid containingcylinder |1|, having one end thereof pivoted to the table frame a piston|12 movable Within the cylinder, a fluid bypass |13, and a piston rod|14 pivotally secured to lever on shaft |68'.

The swinging sheet guide 12 is actuated by rod |16 having a slotted endpivotally carried by offset pin |11 on lever |68.

Air suction means are provided by cylinder pump |18 pivotally mounted atone end to the table frame, the piston rod |19 being pivotally securedto lever |80 on shaft |8I. Said shaft is driven by sprocket |82, chain|83, and a second sprocket |82 on shaft 90. Suitable flexible conduits|84 are connected to the cylinder pump |18 and to the suction bar 63,provision being made for movement of the conduits during reciprocationof the carriage 62.A A spring |18 may be secured to the pump and to thetable frame to assist in raising the pump during rotation of lever |80.

The binding means is actuated by cam wheels |85 and |85.' secured toshaft |8|, the cams |86 and |81 being adaptedy to contact cam roller |88on rods 11 to urge said rods and the binding frame 16 gradually downwardand to accelerate the upward return thereof.

The rack 86 of the flopper mechanism is suitably mounted for verticalmovement and is normally urgedr downwardly by spring |89. A cam roller|90 is provided on the lower end of the rack and ridesv cam wheel |85 tobe contacted by cam |9| for raising the rack and rotating the floppershaft 84, in one direction, the spring |89 causing rotation in thereverse direction.

Obviously, all the moving parts are so arranged and synchronized thatthey will perform their functions at the proper time and in the propersequence. We have shown in` dotted lines a rack |92, on which thevarious flat sheets may be placed prior to feeding into the machine. Itis understood that any suitable rack or other means may be provided forthis purpose and we do not intend to be limited to what we haveillustrated.

In operating the machine, the operator takes a position in front of theintroducing table 5 and places single sheets on the table positioningthe sheet against the shoulder 8 and the guide 9. With the motoroperating the feed belts |2 are continuously moving and at the propermoment the introducing table will be raised and the belts which extendover a portion of the introducing table 5' will contact the sheet andmove it along the table. In feeding the initial sheet for each set it isnot desired to apply an adhesive or carbon paper and therefore as soonasthe operator places this initial sheet on the introducing table hepresses down on the foot pedal I|8 to remove the adhesive applying meansfrom the path of the amasar sheet. AThe foot pedal will also actuatgl aYcontrol for preventing "carbon paper feed and the initial sheet willpass through the feedingjmeans, be perforated between discs I3 and. Handbe transferred to and aligned on the receiving table 49. After thisfirst sheet has passed the adhesive applying means and as the followingsheet yis introduced, the operator releases the `foot pedal and thecarbon paper feed means willremain inoperative until detent |50 isreleased from the drum |52 by passing out through s1ot'|5|. This willclose the mercury switch |41 but will not `necessarily start thecarbonpaper feedingfmeanssince positive actuation of such means is also.dependent on a sheet passing over the light lr y from the incandescentbulb |40. y

Upon release of the foot pedal and insertion of additional individual atsheets on theintroducing table the device will operate in a normalmanner, that is, the sheets will be perforated, adhesive applied andwhen passing between the photoelectric cell and the incandescent bulbi,a predetermined amount of carbon paper will befed to the' carbon paperreceiving table the amount of carbon paper fed depending on the lengthof the at sheet and consequently on the length of time that the lightray is interrupted.

The moment the light ray is unobstructed the carbon paperfeed willstopand the table 41-Will be quickly rocked to cut the carbon paper andraise the cut portion to close r proximity vwith the flat sheet which isin alignment therewith. At the same moment the sheet pickup or suctionbar 63 on the reciprocating carriage 62, having moved to a position overthe adhesive bearing edge of the fiat sheet is quickly depressed at thatpoint by cam 10 to cause the suction bar to firmly press the sheet andcarbon together against the table 41, the carbon paper adhering toktheat sheet.

In Fig. '7 is shown a preferred method of adire-- sive application, twostripes |93 of adhesive-being applied to the at sheets, the carbon paperbeing affixed to the inner stripe. l

The flat sheet with carbon paper attached `will adhere to the suctionbarY which isy movedl across the receiving table 49, the sheets beingaligned by guides l58.and 59 and binding fingers 8|),` Aand the bindingframe 16 is depressed carrying with it the reciprocating carriage 62,the hOOkedpOrtions 82 of the fingers bearing iirmly again'st'thesheets,

and the suction being broken'topermit deposit of the sheets.

As additional sheets are deposited" entire re-v ceiving table the outerstripe of adhesive is pressed firmly against preceding sheetsl and asetof any desired number of sheets and carbons may be formed. f

As sheets accumulate on the receiving table 49 said table lowersautomatically and is restrained against upward movement' by dog 54 whichmay be manually released to permit return of the table 49 to raisedposition when the sheets have been removed. f

Between each set, the-initial operation, that of depressing the footpedal-to prevent adhesive applying and carbon paper feeding, isrepeated. It is clearly obvious that we have provided a device in whichany number of at sheets. and carbons may be assembled into r sets,'inwhich feeding'of a flat sheet into themachinewill-insure positiveland automatic feeding of apredetermined quantity of carbon paper unlessthe operator desires to manually prevent such feeding, that as long assheets are not introduced Ano car- 'bon is being fed and there isnothing Wasted.
